Abstract

An external mix air atomizing spray nozzle assembly having a nozzle body formed with liquid and air passages, a spray tip at a downstream end of the nozzle body having a nose portion that defines a liquid discharge orifice, and an air cap mounted in surrounding relation to the spray tip nose portion. The air cap defines an annular pressurized air orifice about the spray tip nose portion and a plurality of angled air passages disposed radially outwardly thereof. Pursuant to the invention, the spray tip nose portion has a frustoconical end tapering inwardly in a downstream direction which enhances air entrainment and minimizes liquid turbulence in a zone immediately in front of the air cap and around the spray tip nose portion to prevent undesirable build up of spray material on the exposed end surfaces of the spray tip nose portion and air cap.
